Bring less stuff. I ditched treestands altogether about 3 years ago...now I just bring a small folding stool. I also switched to shooting barebow last spring...no need for an extra release (or, any release!) and with no site, I dont need a rangefinder. I have a small backpack, in it is a drag rope, 2 knives (big & small) some extra clothes depending on weather, a bottle of water, a snack, some zip ties for tagging, 2 flashlights (incase one dies)...and sometimes some calls and rattles. Thats really about all I need, I found that, the more crap I bring in...the less actually gets used, and I have to haul it back out.
Im not saying you need to switch your style, but instead look at what you have, and what you REALLY need to haul in.
